This is the whole function process:
Code:function process() { global $order, $currencies, $db; $order_total = $this->get_order_total(); $od_amount = $this->calculate_deductions($order_total['total']); $this->deduction = $od_amount['total']; if ($od_amount['total'] > 0) { reset($order->info['tax_groups']); $tax = 0; while (list($key, $value) = each($order->info['tax_groups'])) { if ($od_amount['tax_groups'][$key]) { $order->info['tax_groups'][$key] -= $od_amount['tax_groups'][$key]; $tax += $od_amount['tax_groups'][$key]; } } if ($od_amount['type'] == 'S') $order->info['shipping_cost'] = 0; $order->info['total'] = $order->info['total'] - $od_amount['total']; if (DISPLAY_PRICE_WITH_TAX == 'true') { $od_amount['total'] += $tax; } if ($this->calculate_tax == "Standard") $order->info['total'] -= $tax; if ($order->info['total'] < 0) $order->info['total'] = 0; $order->info['tax'] = $order->info['tax'] - $tax; $group_query = $db->Execute("select customers_group_pricing from " . TABLE_CUSTOMERS . " where customers_id = '" . (int)$_SESSION['customer_id'] . "'"); $group_discount = $db->Execute("select group_name, group_percentage from " . TABLE_GROUP_PRICING . " where group_id = '" . (int)$group_query->fields['customers_group_pricing'] . "'"); $this->output[] = array('title' => $this->title . ':' . ' ' . $group_discount->fields['group_name'], 'text' => '-' . $currencies->format($od_amount['total'], true, $order->info['currency'], $order->info['currency_value']), 'value' => $od_amount['total']); } }
